' (iii whom it may concern:

Be it known that I, EDWARD C. PURNELLE, a citizen of the United States, and a resident of Douglas, in the county of Cochise and State of Arizona, have invented a new and Improved Cooler, of which the following is a full, clear, and exact description.

My invention relates to the type of cool ers in which evaporation is utilized to effect the cooling, and in which provision is made for saturating a cloth or the like held on the exterior of the cooler.

()bjects of my invention are to provide an improved cooler of the indicated character, comprising a safe provided with efficient air-circulating and ventilating means; to provide a novel, improved manner of securing cloth to be moistened; to provide a novel means for maintaining the cloth saturated; to provide a door having a member to catch any drip from the cock of the water tank when the door is open; to utilize the said drip for saturating a cover provided on the door; and to provide a novel drip pan to carry off the water dripping from the saturated covering.

Other objects will appear from the more specific description following.

Reference is to be had to the accompany ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation partly in section, the door of the safe forming part of the cooler being shown open, and the covering to be saturated being for the most part broken away; Fig. 2 is an inverted diagrammatic view of the cover of the water tank, as indicated by the line 22 of Fig. 1; Fig. 3 is a perspective view of a cooler constructed in accordance with my invention, a portion of the fabric covering being broken away; Fig. 4: is a horizontal section on the line %i of Fig. 1; Fig. 5 is a detail horizontal section on the line 5-5 of Fig. 1; and Fig. 6 is a fragmentary side view showing the manner of securing the upper edge of the fabric covering.

In constructing a cooler in accordance with the illustrated example, the body 10 is made generally of cylindrical form, and constructed for its major portion to constitute a safe to receive various perishable articles. The said safe is provided with an opening defined by a door frame 11, to

which a door 12 is hinged, as at 12 Suitable means is provided for suspending the cylinder in vertical position. Said means may consist of brackets l0 on the cooler, adapted to connect with the suspension cords 13 by S-hcoks 13, or like means.

The safe is provided with a suitable number of shelves l l, the bottom 1 1 constituting an additional shelf or support. Above the top 15 of the safe a water tank 16 is formed in the body 10, there being a chamber 17 between the top 15 of the safe and the bottom 16 of the said water tank. Said chamber 17 is formed with an enlarged opening 17 directly below the cock 18 of the water tank, so that the chamber may conveniently be utilized for holding a drinking vessel or like articles. Additional ventilating holes 17 are formed in the side walls of the chamber 17.

A covering 19, preferably of suitable fabric, is provided and is adapted to be saturated, whereby to cool the water tank and safe by evaporation. In order to provide for maintaining the covering 19 in saturated condition, a water receiver 20 is provided on the top of the removable cover 2 10f the water tank 16. The receiver 20 may be supplied with water in any suitable or convenient manner, there being indicated in the present instance a water pipe 22 delivering to the said receiver. The cover 21 is conical, the receiver 20 being mounted at the apex, and in the base of said receiver holes 23 are formed, so that water will flow out onto the cover 21 and be disseminated over the latter to the fabric covering 19. The lower edge of the cover 21 is preferably corrugated to more effectively distribute the water.

To fasten the covering 19 at the upper edge, a wire band 24: is provided, which is threaded through the edge of the fabric and bound tightly around the water tank adjacent to the lower edge of the cover 21. To secure the fabric adjacent to the sides of the door frame 11, eyes or staples are provided, which may receive wires or any other suitable fastening means engaging the cover fabric.

ll-provide means on the door 1 to se *1a rately secure a. covering 19 of fabric to the exterior surface of the door. A. portion of said fabric is indicated in Fig. 8. The securing means may consist of loops or eyes 26 similar to the elements 25, so that the fablOO ric may be fastened by a wire 24*, or equivalent means engaging said eyes 26.

The cover 21 desirably is covered with burlap 19 which may overlap the upper end of the burlap covering 19.

To provide a shelf while the safe door is open, for temporary use while placing articles in the safe or in removing articles, and also in order that any drip from the cock 18 may not fall on the hands of a person placing articles in the safe, or removing the same, and may not fall on the said articles, I provide a horizontal tray 27 on the inner side of the door 12, so that the said tray will be brought to a position beneath the cock 18 when the door is swung open. Adjacent to the front end of the tray 27 the door is provided with an outlet hole 28 for any water collecting in the said shield. The said hole also may constitute a ventilating opening. A similar opening 29 is formed at the lower end of the door for ventilation, and both of these openings may be covered with Wire netting in practice. A suitable handle 30 is provided on the door. Any drip or overflow from the shelf or tray 27, serves to moisten the door covering 19 said covering will also receive water from the portion of the covering 19 above the door. In any event, the cooling of the door is merely supplemental to the cooling of the remainder of the structure.

In connection with the safe, a vertical air tube 31 is centrally disposed, open at its inner end within the safe, the open upper end projecting above the top 15 of the safe.

Lateral branch pipes 32 extend outwardly through the side walls of the safe, the outer ends being desirably protected by a wire netting 33. Additional branch pipes 32 lead forwardly in the direction of the door opening 11. The shelves 1% may have supporting lugs or brackets 14 at the under sides resting on the branch pipes 32, 32*. Above the top shelf 14 an additional ventilating opening covered by a wire netting 34 (Fig. 1) may be provided. The upper open end of the central air tube 31 may be covered by wire netting as at 35.

By the described arrangement of the ventilating pipes, fresh air will tend to enter therein through the sides and top of the safe and in being cooled will tend to fall to the bottom and escape through the bottom pipe. Moreover, the opening of the door will tend to draw fresh air through the pipes and through the lower portion of the safe. The extent of the air circulation thus induced will be sufiicient to promote ventilation without materally decreasing the effectiveness of the cooling means.

In order to catch the drip from the fabric covering, a drip pan 36 is suspendedbelow the bottom of the safe, the suspension means consisting in the present example of loops 37 on said drip panadapted to be detachably engaged with headed studs 38011 the safe. The drip pan is made funnelshape, and at its center is an outlet pipe or nipple 89, from which in practice, a pipe or tube may lead to any desired point.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

1. A cooler comprising a safe, means whereby the safe may be cooled, air circulating means for said safe, consisting of a vertical air pipe, open at its inner end within the safe and extending at its upper end above the safe, and lateral branch pipes leading outwardly from said central pipe, through the sides of the safe to the exterior, and shelves supported on the said branch pipes around the vertical pipe.

2. A cooler comprising a safe, means whereby the safe may be cooled and air-circulating means for said safe consisting of a vertical air pipe, open at its inner end with in the safe and extending at its open upper end above the safe, and lateral branch pipes leading outwardly from said central pipe through the sides of the safe to the exterior.

3. A cooler including a body, a covering on said body, adapted to be saturated, a conical top for said body, presenting a plain surface and having a base rim presenting'an annular series of approximately vertical corrugations around the same, means for securing the covering to the cooler adjacent to the said corrugated base rim at the top, and means for delivering water onto said top.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
